4.The clinical value of NT-ProBNP in evaluation the severity of heart failure
Chinese Journal of Primary Medicine and Pharmacy 2013;20(15):2250-2251
Objective To explore the clinical value of N-terminal prosoma of B-type natriuretic peptide (NT-ProBNP) in assessing the heart function of the patients with chronic heart failure.Methods 94 inpatients diagnosed as chronic heart failure were divided into 4 groups (Ⅰ,Ⅱ,Ⅲ,Ⅳ) according to the cardiac function of NYHA Functional Class(NYHA-FC),and 5 inpatients with normal cardic function were also selected as control group.The plasma NT-ProBNP was detected.The results of heart color ultrasound was collected.Results In patients with heart failure,left ventricular end-diastolic dimension(LV) increased following the increase of plasma NT-ProBNP level.Among NYHA-FC groups,NT-ProBNP levels were different,which increased as the NYHA-FC upgrades.Spearman correlation analysis showed that NT-ProBNP had good correlation with both LV and NYHA-FC(r =0.453,P <0.01 ;r =0.538,P < 0.01).There was also good correlation between LV and NYHA-FC(r =0.322,P < 0.01) ;but the correlation was slightly lower than the previous.Conclusion NT-ProBNP can reflect the level of ventricular remodeling and the severity of the cardiac decompensation in chronic heart failure patients.
5.THE DETERMINATION OF THE GLUCOCORTICOID RECEPTOR IN THE HEPATIC CYTOSOL OF INTACT RATS AND THE CHANGES OF THE RECEPTORS AFTER SCALDING
Academic Journal of Second Military Medical University 1982;0(02):-
The glucocorticoid receptor of hepatic cytosol of rat was determined by the exchange assay in the presence of endogenous corticosterone. The condition of ex-chame was 0℃ , 4.5~5 hours. The dissociation of corticosterone-receptor complex was about 90% under such a condition. The effect of the endogenous corticosterore on the assay was evaluated by the measurement of [3H]-dexamethasone binding after preincubation of the liver cytosol from adrenalectomized rats with different amounts of corticosterone. The results indicated that, at a corticosterone concentration of less than 6 nM the error of the specific binding capacity (Ro) of [3H]-dexa-methasone was no more than 10%,and the apparant dissociation constant (Kd) was essentially unchanged. The Ro and Kd of glucocorticoid receptor of the hepatic cytosol of normal and scalded rats were measured by this method. The Ro was decressed in the scalded rats. The levels of Ro in hepatic cytosol from rats after 1, 12,24, 36 hours and 5 days of scalding were 76.4?15.2%,70.6?22.0%79.7?5.8%, 113.0?24.8% and 102.9 ?17.6% (mean?SD) of the control group respectively. The apparant Kd slightly increased 1 hour after scalding. The possible mechanisms of the above changes were discussed.

8.Advances in relevant prognostic factors of primary central nervous system lymphoma
Journal of Leukemia & Lymphoma 2009;18(11):694-696
Primary central nervous system lymphoma (PCNSL) is a rare type of malignant lymphoma which originates in the central nervous system without spreading to other systems. It is more predisposable to immunodeficient individuals. However, an increase in the incidence of PCNSL has been also observed in the healthy population in recent years. PCNSL has short phase of clincal release, and easy to relapse with poor prognosis. Some studies have shown that relative prognostic factors were associated with age, performance status, the radiotherapy and chemotherapy modalities, the response to early adminstration of the glucocorticoid,tissue pathologic type and the molecular biologic marks.
